carb rebuilds?

hey guys
About how often does a carb need to be rebuilt? My 77 f-150 w/400 has a hard time taking off from a stop when its cold an I thought this might be the cause. I have already replaced the choke.
Thanks
David

The carb that was on my 78 400 went 317,000 Km without a rebuid,and it worked great.
I think the key is *constant use*.
If left sitting ,things will dry out and need replacing.

Yes, sitting idle and not running is bad for a carb. If you are running the stock 2bbl Motorcraft carb on your 400, I would consider not bothering to rebuild it. It is a bit more expensive, but there are a lot of benefits to getting a new carb, especially if your old one has a lot of miles on it and you are not an experienced carb mechanic.

Thanks guys,
My carb is the stock motorcraft but I don't know how old it is. I bought the truck off an elderly man last summer. I think they said that they werent driving it much but that was a while back. I drive it most every day. Thanks again.
David

These carbs are easy to rebuild. Take your time on the first one and pretty soon you will be able to do it with a blindfold on.

Could be that the timing is too slow, or that the accelerator pump in the carb is shot. Check the timing. Should be around 10 to 12 BTDC.
